Product Information

• The RAVAS-1100 is a weighing Hand Pallet Truck designed for accurately weighing loads during material handling operations.
• It features a touch panel indicator and various functions for precise weighing measurements.
• The system is powered by an exchangeable battery pack, providing a weighing time of approximately 35 hours on a system without a printer.
• The RAVAS-1100 is manufactured by RAVAS Europe BV, located in Zaltbommel, Netherlands.
• The product is 100% recyclable, with parts processed and disposed of in an environmentally responsible manner.

Product Usage Instructions

Taking the System into Operation

• To activate the weighing system, turn it on using the on/off key on the terminal.
• Allow the electronics and load cells to reach the operational temperature, which takes approximately 3 to 5 minutes.
• Note that inaccuracies of up to ca. 0.3% may occur before reaching the operational temperature.
• It is recommended not to lift loads before executing the zero-point correction.

Power Supply

• The system is powered by an exchangeable battery pack. For legal trade systems, the power supply is through a fixed-mounted battery.
• A completely charged battery provides a total weighing time of about 35 hours (on a system without a printer).
• When the battery level indicator shows a low battery for 1 or 2 minutes, the weighing system switches off automatically.
• It is strongly recommended to charge the empty battery directly with the supplied charger.

Follow the charging instructions below precisely to maximize the lifetime of the battery:

1. Insert the battery into the charger module. For legal trade systems, connect the charger cable to the system.

2. Plug in the charger adaptor into mains voltage 220-240VDC.
   The red LED on the charger adaptor indicates that the charger is charging the battery. Charge the battery for at least 6 hours to prevent loss of battery capacity.

3. An empty battery will be fully charged after approximately 6 hours. When the red LED turns off, the battery is fully charged.
   The charger switches off automatically to prevent overloading the battery.

4. Disconnect the charger adaptor plug from the mains voltage.

5. After removing the charger adaptor plug, directly remove the battery from the charger module. For legal trade systems, directly remove the charging cable from the system after removing the adapter from the charger.

6. To charge the next battery, start at step 1 again.

• If you use the system in shift work or if the system has a built-in printer, it is recommended to purchase a supplementary battery pack.

Proper Load Lifting

• When lifting loads, ensure that the weight is lifted freely without touching the housing of the indicator or other pallets. The most accurate weighing result is achieved when the center of gravity of the load is placed between the forks. Non-centric loading may cause forks to tordate and bend, resulting in higher inaccuracy. Legal for-trade versions have a level control that switches off the indicator with non-centric loading or a tilted position that affects weighing accuracy.

The weighing Hand Pallet Truck

Taking the system into operation

• To activate the weighing system, turn it on using the on/off ( 1 ) key on the terminal.
• After 3 to 5 minutes the electronics and load cells have reached the operational temperature. Before this, inaccuracies of up to ca. 0.3% may occur.
• It is recommended not to lift loads before the zero-point correction has been executed.

Power supply

• The power supply to the system takes place through an exchangeable battery pack.
• Note: For legal trade systems the power supply to the system takes place through a fixed-mounted battery.
• With a completely charged battery, the total weighing time is about 35 hours (on a system without a printer).
• IN is shown for 1 or 2 minutes, the weighing system switches off automatically. It is strongly recommended to charge the empty battery directly with the supplied charger.
• In order to maximize the lifetime of the battery, follow the charging instructions below precisely:

1. Insert the battery into the charger module. Note: For legal for trade systems connect the charger cable to the system
2. Plug-in the charger adaptor plug, into mains voltage 220-240VDC. The red LED on the charger adaptor is lit to indicate that the charger is charging the battery. When charging, it is necessary to charge the battery for at least 6 hours. This will prevent loss of battery capacity.
3. An empty battery will be fully charged after approximately 6 hours. When the red LED turns off, the battery is fully charged. It is not possible to overload the battery because the charger switches off automatically.
4. De-connect the charger adaptor plug from the 220-240VDC mains voltage.
5. After taking out the charger adaptor plug, directly remove the battery from the charger module.
   • Note: For legal for trade systems directly remove the charging cable from the system after removing the adapter from the charger.
6. For charging a next battery, start at step 1 again.

• If you use the system in shift work or if the system has a built-in printer, it is recommended to purchase a supplementary battery pack.
• The weight must be lifted freely: without touching the housing of the indicator or other pallets:
• The accuracy of the weighing system diminishes with circa 0.1% per degree starting from a tilted position of 2°. This effect also occurs with pits/pot-holes in the floor. An even floor is optimal. The system will be produced with an electrical level switch. When the forks are out of level with more than 2 degrees, the indicator will display.
• The most accurate weighing result is obtained when the centre of gravity of the load is placed between the forks. With an non-centric loading, the forks will tordate and bend. This may result in a higher inaccuracy. With legal for trade versions, the level control will switch off the indicator with a non-centric loading or a tilted position that influences the weighing accuracy.
• Temperature range: between -10 and +40° C the maximum inaccuracy is 0.1% of the weighed load. Outside this range, inaccuracies of up to 0.3% may occur.
• Fast temperature changes must be avoided because it will cause condensation in the electronics. During acclimatisation the weighing system must be switched off.

Maintenance

• The maintenance guidelines for normal pallet trucks apply to the chassis of the mobile weighing system. From experience we know that the integrated weighing system still functions when the chassis is damaged by overloading.

Main guidelines:

• Because the steering wheels are mounted in the front, pulling of the pallet truck is preferred above pushing it.
• When the lifting mechanism is not used, the handle should be kept in the neutral, middle, position. This prolongs the life span of the sealings.
• The weighing system meets up to the protection class IP65. This means that dust or moisture (rain or water beam from all sides), will not influence the operation of the electronics. However, high-pressure cleansing in combination with warm water or chemical cleansers will lead to the entry of moisture and therefore negatively influence the operation of the system. In case of a stainless steel chassis you should never use a detergent that contains chloride, otherwise you will get brown spots on the chassis.
• Only specialists may undertake any welding. This is to avoid damage to electronics and load cells.
• The bearings of the wheels (non-polyurethane) and the pivoting points of the levelling bar of the loading wheels must be cleansed and greased regularly.

Mobile Weighing system

• A mobile weighing system is a mobile scale. This means that the owner should consider the same maintenance as applicable with standard stationary scales.
• A yearly inspection, by an authorized service provider, is recommended. And in case the scale is stamped ‘legal for trade’ then the weighing system should be re-stamped in accordance with the metrological regulations in the country of use.
• When your company is ISO certificated, it is very likely that all measuring devices should be checked more regularly than once a year (i.e. ½ year or ¼ year). For an easy overview you can fill out the following maintenance sheet.

Based on these recommendations we are convinced that your mobile weighing system will work accurately and reliably for a very long time.

Touch panel indicator

The display
By means of three-pointer bars the display shows:

• the weighing system (including load) is stable
• the weight shown is negative
• NET ◄ the display shows the net weight

The display indications

• The minus sign lights in the display. The following indications can be shown in the display:
• HELP 1 The weighing system has been overloaded.
• HELP 2 Taring of negative weight.
• HELP 3 Negative signal from the load cell on AD converter / tilted position.
• HELP 4 The tare value entered (manually) is too high. Press key PT again to delete this help message and key in a lower tare value.
• HELP 5 Totalling memory full.
• HELP 6 No Bluetooth connection (only RF-systems).
• HELP 7 Signal from the load cell on AD converter is too high.
• HELP 8 Tilted position (only RF-systems).
• HELP 9 Low bat on transmitter (only RF-systems).
• LO-BA or The battery voltage level (indicator) is running low. The battery has to be charged.

The touch panel

• Each key has an operational and an entry function.

• Operational function Entry function

  • zero setting and automatic tare confirm and digit to the left

• tare entry decreasing flashing digit

  • totalizing increasing flashing digit

• on / off clear

Important

• Operation of a key is not accepted unless the weighing system is stable (and the sign “load stable” lights up). This means that the indicator only executes commands with a stable load.

Warning

• When the weighted load surpasses the pre-set maximum, the display shows: “HELP1”. In order to prevent damage to the indicator or load cells, the weighing system must be unloaded immediately.

Tilted position

• With the approved version of the weighing system, the help display shows small bars when this system is in a tilted position larger than 2°. In this case, the weighing system must be placed in a horizontal position.
• After this, the system continues executing any commands.

Functions indicator

Graduation

• The graduation of the indicator depends on the weighted load:
• from 40 to 2000 kg, the weight is shown in 2 kg steps, or
• from 20 to 2000 kg the weight is shown in 1 kg steps

Before weighing: check zero point

• Before each weighing it is necessary to check whether the system is unloaded and free.
• The indicator is fitted with an automatic zero correction.
• This means that small deviations of the zero point will be corrected automatically.
• If the indicator does not determine the zero point automatically, it must be done manually using the 0/T key.

Gross weighing

• After lifting a load, the display shows the gross value of the weighted load.

Net weighing: automatic tare

• The indicator offers the possibility to reset tare weights to zero automatically.
• This way added or subtracted weights can be determined.
• After taking it, the display continues in the smallest step.
• Lift load.
• Press key 0/T.
• The indicator is set to zero.
• The “NET” pointer shows that a tare weight is activated.
• Place or remove the net load.
• The display shows the net value of the weighted load.
• When removing load, this is a negative value.
• By executing a zero setting in the unloaded position, the system will return to the standard weighing mode.

Net weighing: manual tare entry

• A tare weight can be entered at any moment, meaning in either a loaded or unloaded situation. For higher accuracy, a tare weight can be entered with a smaller graduation step, independent of the applied load and the active graduation of the indicator.
• A tare weight larger than the so-called MAX1 of the weighing system will not be accepted by the indicator. The MAX1 is the value of the weight of the first range; in the standard version 200 kg (see 3.1.). If a larger weight is keyed in, the display shows HELP4”. Upon pressing the key PT, this HELP indication disappears.
• Press the PT key.
• The display shows the current tare value.
• The digit on the right flashes.
• Press ENTER(↵) for three seconds if the current tare value is required.

Or

• Press the PT key.
• Press the ∧ key to go up a value or press the ∨ key to go down a value until the required value is reached.
• Press ENTER (↵) to change the next value.
• Repeat this procedure until the required tare value is displayed.
• To activate the tare weight, but without storage in the memory: press ENTER(↵) for three seconds.
• The tare weight is activated.
• The “NET” pointer lights up.
• When the system is loaded at this moment, the net value appears in the display.
• When the system is unloaded, the read-out displays the given tare value negatively.
• The keyed-in value remains active until the system is turned off, a new tare weight is entered, a new load is tared (see 3.4.) or by resetting the tare value to zero:
• The weighing system is loaded: press the PT key for two seconds. The tare value is set to zero and the system returns to the standard weighing mode.
• The weighing system is unloaded: press the 0/T key. The tare value is set to zero and the system returns to the standard weighing mode.
• To activate the tare weight and store it in memory: go through all the digits by pressing ENTER(↵).
• The tare weight is activated and stored in the memory.
• The “NET” pointer lights up.
• When the system is loaded at this moment, the net value appears in the display.
• When the system is not loaded, the tare value input is displayed negatively.
• The keyed in value remains active, even if the system is turned off, until a new tare weight is entered, a new load is tared (see 3.4.) or by resetting the tare value to zero:
• The weighing system is loaded: press the PT key for two seconds. The tare value is set to zero and the system returns to the standard weighing mode.
• The weighing system is unloaded: press the 0/T key. The tare value is set to zero and the system returns to the standard weighing mode.

Totalling

• The indicator offers the possibility to add up weighings and show the total weight. When a tare weight is active, the net weight is added up automatically.
• Load the system with the weight that should be added.
• Press the Σ key to add the weighed load to the total weight.
• The value of the display is stored and added in the memory.
• In turn, the indicator shows the sequence number (number of weighings) and the (sub)total.
